I was looking recently for a nice way to generate Fluent Builder pattern code in Eclipse. I tried two plugins
- Builder Pattern Eclipse Plugin (https://github.com/henningjensen/bpep)
- fluent-builders-generator-eclipse-plugin (https://code.google.com/p/fluent-builders-generator-eclipse-plugin/)
but both are not enough for me. I was looking for a plugin with ability to generate Fluent Builder for immutable class with final fields. Unfortunately both mentioned plugins work only with mutable classes.
So I decided to write my own plugin as a fork of BPEP.
Below you can see some example class and builder generated for it by FBGEP – Fluent Builder Generator Eclipse Plugin.
public class Person {
private final String firstname;
private final String lastname;
private final String address;
private final String zipcode;
private final String city;
public Person(String firstname, String lastname, String address,
String zipcode, String city) {
this.firstname = firstname;
this.lastname = lastname;
this.address = address;
this.zipcode = zipcode;
this.city = city;
}
}
Class with generated fluent builder:
public class Person {
private final String firstname;
private final String lastname;
private final String address;
private final String zipcode;
private final String city;
public Person(String firstname, String lastname, String address,
String zipcode, String city) {
this.firstname = firstname;
this.lastname = lastname;
this.address = address;
this.zipcode = zipcode;
this.city = city;
}
public static class PersonBuilder {
private String firstname;
private String lastname;
private String address;
private String zipcode;
private String city;
public PersonBuilder withFirstname(String firstname) {
this.firstname = firstname;
return this;
}
public PersonBuilder withLastname(String lastname) {
this.lastname = lastname;
return this;
}
public PersonBuilder withAddress(String address) {
this.address = address;
return this;
}
public PersonBuilder withZipcode(String zipcode) {
this.zipcode = zipcode;
return this;
}
public PersonBuilder withCity(String city) {
this.city = city;
return this;
}
public Person build() {
return new Person(firstname, lastname, address, zipcode, city);
}
public static PersonBuilder person() {
return new PersonBuilder();
}
}
}
